LAS IMAGENES MEDICAS (IM) COMO LA TOMOGRAFIA AXIAL COMPUTARIZADA (TAC) SON DE CADA VEZ MAYOR USO EN EL TRATAMIENTO DE PATOLOGIAS. EN PARALELO, EL USO DE TECNICAS DE SIMULACION COMO EL METODO DE LOS ELEMENTOS FINITOS (MEF) EN EL CASO QUE NOS OCUPA, SE EXTIENDE A UN ABANICO DE APLICACIONES CADA VEZ MAS AMPLIO. ASI, RESULTA CADA VEZ MAS FRECUENTE ENCONTRAR ESTUDIOS ENCAMINADOS A CREAR MODELOS MEF A PARTIR DE LAS IM, SIENDO ESTE UN PASO CLAVE PARA LLEVAR A CABO SIMULACIONES NUMERICAS ¿PATIENT-SPECIFIC¿ QUE AYUDEN EN LAS TAREAS DE DIAGNOSTICO DE PATOLOGIAS, PLANIFICACION DE INTERVENCIONES QUIRURGICAS, PERSONALIZACION DE IMPLANTES, ETC. LAS TECNICAS ACTUALES DE GENERACION DE UN MODELO MEF A PARTIR DE LA IM NO ESTAN COMPLETAMENTE AUTOMATIZADAS Y SUELEN REQUERIR LA PARTICIPACION DE ESPECIALISTAS DEL CAMPO MEDICO EN EL PROCESO DE SEGMENTACION DE LA IMAGEN EN QUE SE IDENTIFICAN LOS DIFERENTES ORGANOS REPRESENTADOS, LO QUE LIMITA NOTABLEMENTE SU USO. _x000D_ _x000D_ ESTE PROYECTO PRETENDE DESARROLLAR UNA HERRAMIENTA DE ANALISIS BASADA EN EL MEF QUE PERMITA LA SIMULACION DEL CONJUNTO PROTESIS-HUESO, UTILIZANDO MODELOS DE ELEMENTOS FINITOS (EF) ¿PATIENT-SPECIFIC¿ OBTENIDOS DIRECTAMENTE A PARTIR DE LAS IM DEL PACIENTE, A FIN DE DETERMINAR A TRAVES DE UN ANALISIS PERSONALIZADO LA PROTESIS A IMPLANTAR QUE RESULTE MAS ADECUADA._x000D_ _x000D_ LA OBTENCION DIRECTA DEL MODELO MEF A PARTIR DE LA IM SE LOGRA EMBEBIENDOLA DENTRO DE UNA MALLA CARTESIANA DE EF DE ESTRUCTURA DE DATOS JERARQUICA QUE SIMPLIFICA EL REFINAMIENTO DE LA MALLA Y ACELERA EL CALCULO. EL PROCESO ASIGNA A CADA UNO DE LOS VOXELS CONTENIDOS EN CADA EF PROPIEDADES DE MATERIAL EN FUNCION DEL NIVEL DE COLOR DEL VOXEL, QUE SERAN LUEGO CONSIDERADAS EN LA GENERACION DEL MODELO NUMERICO. EL PROCEDIMIENTO PERMITE QUE DENTRO DE UN EF COEXISTAN UNA ZONA DE VOXELS DE LA IM Y OTRA CORRESPONDIENTE A UN SOLIDO DEFINIDO POR UNA SUPERFICIE DE CAD, CON DIFERENTES PROPIEDADES DEL MATERIAL EN CADA ZONA. ESTA PARTICULARIDAD PERMITE LA FACIL MODELIZACION NUMERICA DE LA INTERACCION HUESO-IMPLANTE. _x000D_ _x000D_ CON EL OBJETIVO DE PODER MODELAR LOS MOVIMIENTOS ENTRE EL HUESO E IMPLANTE (CUANDO TODAVIA NO SE HA PRODUCIDO LA OSEOINTEGRACION) O ENTRE DIFERENTES PARTES DE UN IMPLANTE, SE IMPLEMENTARAN ALGORITMOS DE CONTACTO ESPECIFICAMENTE ADAPTADOS AL CASO DE MALLAS CARTESIANAS INDEPENDIENTES DE LA GEOMETRIA. _x000D_ _x000D_ ADEMAS DE PODER ANALIZAR CUAL DE LOS IMPLANTES DISPONIBLES EN EL MERCADO SE AJUSTA MAS AL PACIENTE, ESTE PROYECTO PLANTEA EL OBJETIVO DE OBTENER LA CONFIGURACION GEOMETRICA OPTIMA ESPECIFICAMENTE ADAPTADA A LAS CARACTERISTICAS DEL PACIENTE OBTENIDAS A TRAVES DE SU IM. ASI, LA HERRAMIENTA DISPONDRA DE ALGORITMOS DE OPTIMIZACION DE FORMA BASADOS EN INFORMACION DEL GRADIENTE DE LA RESPUESTA ESTRUCTURAL EVALUADO A TRAVES DE TECNICAS DE ANALISIS DE SENSIBILIDADES ADAPTADAS AL USO DE MALLAS CARTESIANAS. _x000D_ _x000D_ PARA VALIDAR LA HERRAMIENTA, ESTA SE USARA EN EL ESTUDIO DE IMPLANTES DENTALES DE CARGA INMEDIATA QUE PERMITEN LLEVAR DIENTES FIJOS SOBRE LOS IMPLANTES INMEDIATAMENTE DESPUES DE SU COLOCACION. DADO QUE NO EXISTEN CRITERIOS RIGUROSOS PARA ESTABLECER SI ES IDONEO COLOCAR ESTOS IMPLANTES, LA HERRAMIENTA PERMITIRA AYUDAR A ESTABLECER ESTOS CRITERIOS, A DETERMINAR LA INFLUENCIA DE LAS CARACTERISTICAS GEOMETRICAS DEL IMPLANTE EN LA CAPACIDAD DE TRANSMISION DE CARGA DEL CONJUNTO HUESO-IMPLANTE E INCLUSO A DETERMINAR LA GEOMETRIA IDONEA DE ESTOS IMPLANTES EN CADA PACIENTE.

MEDICAL IMAGES (IM) SUCH AS COMPUTED AXIAL TOMOGRAFIA (CT) ARE INCREASINGLY USED IN THE TREATMENT OF PATHOLOGIES. IN PARALLEL, THE USE OF SIMULATION TECHNIQUES AS THE FINITE ELEMENT METHOD (MEF) IN THE PRESENT CASE EXTENDS TO AN EVER WIDER RANGE OF APPLICATIONS. THUS, IT IS BECOMING MORE AND MORE FREQUENT TO FIND STUDIES AIMED AT CREATING MEF MODELS FROM THE IM, BEING A KEY STEP TO CARRY OUT NUMERICAL SIMULATIONS PATIENT-SPECIFIC THAT HELP IN THE TASKS OF DIAGNOSIS OF PATHOLOGIES, PLANNING OF SURGICAL INTERVENTIONS, CUSTOMISATION OF IMPLANTS, ETC. THE CURRENT TECHNIQUES OF GENERATION OF AN MEF MODEL FROM THE IM ARE NOT FULLY AUTOMATED AND USUALLY REQUIRE THE PARTICIPATION OF SPECIALISTS FROM THE MEDICAL FIELD IN THE PROCESS OF SEGMENTATION OF THE IMAGE IN WHICH THE DIFFERENT BODIES REPRESENTED ARE IDENTIFIED, WHICH SIGNIFICANTLY LIMITS THEIR USE. _x000D_ _x000D_ this PROJECT PRESENT TO DEVELOP ANALISIS TOOLS BASED IN THE MEF that Permits the SIMUATION OF THE PROTESIS-HUESO JUNT, USING FINANCIAL ELEMENT MODELS (EF) PATIENT-SPECIFICDo we OBENT DIRECTLY TO PART OF THE PATIENT IM, in the end of the process of determining the results of a personalised analysis to implement the outcome of the MEF model to be carried out by the end of the year._x000D_ _x000D_ the direct management of the model MEF to take account of the success of a cartesian mall of hierarchical data stRUCTURE that simplifies the reefing of the mall and improves the quality of life. THE PROCESS ASSIGNS TO EACH OF THE VOXELS CONTAINED IN EACH EF MATERIAL PROPERTIES DEPENDING ON THE COLOR LEVEL OF THE VOXEL, WHICH WILL THEN BE CONSIDERED IN THE GENERATION OF THE NUMERIC MODEL. THE PROCEDURE ALLOWS THAT WITHIN AN RU A ZONE OF VOXELS OF THE IM AND ANOTHER ZONE CORRESPONDING TO A SOLID DEFINED BY A SURFACE OF CAD COEXIST, WITH DIFFERENT PROPERTIES OF THE MATERIAL IN EACH ZONE. THIS PARTICULARITY ALLOWS THE EASY NUMERICAL MODELLING OF THE BONE-IMPLANT INTERACTION. _x000D_ _x000D_ with the OBJECTIVE OF MODELING MOVEMENTS BETWEEN WORLD AND IMPLANT (WHY TODAVIE IS NOT PRODUCTED OSEO-integration) OR BETWEEN DIFERENT PARTS OF an IMPLANT, SPECIFICIAL CONTACT ALGORITMTS attached to the case of Cartesian INDEPENDENT MALLAS of GEOMETRY. _x000D_ _x000D_ in addition to being able to analyse which of the IMPLANTS AVAILABLE IN THE MARKETING MORE TO THE PATIENT, THIS PROJECT THE OBJECTIVE TO OBJECTIVE OPTIMAL GEOMETRIC CONFIGURATION SPECIFICED TO THE CHARACTERISTICS OF THE PACIENT OBJECTIVES OBJECTIVE AT THE IM. the tool will have FORMATIONALGORITMS based on the information of the GRADIENT OF THE STRUCTURAL RESPONSE EVALUATE INFORMATION WITH THE TECHNICAL ANALISIS OF SENSIBILITIES ADAPTED TO THE USE OF Cartesian MALLAS. _x000D_ _x000D_ to VALID THE TOOL, this will be used in the DENTAL IMPLANTE IMPLANTS OF IMMEDIATE THAT PERMITED TOOLS FIXED DIENTS ON IMMEDIATAL IMPLANTS Awaiting your COLOCATION. GIVEN THAT THERE ARE NO RIGOROUS CRITERIA FOR ESTABLISHING WHETHER THESE IMPLANTS ARE IDEALLY PLACED, THE TOOL WILL HELP ESTABLISH THESE CRITERIA, DETERMINE THE INFLUENCE OF THE GEOMETRIC CHARACTERISTICS OF THE IMPLANT ON THE CARRYING CAPACITY OF THE BONE-IMPLANT SET AND EVEN DETERMINE THE IDONEA GEOMETRIES OF THESE IMPLANTS IN EACH PATIENT.
